subject: Sds Drills-user Information [print this page] The company Bosh 1st introduced SDS drills or Special Direct System Drills way back in 1975. These power tools are very similar to regular hammer drills but allow the user to have more power and control in terms of hammer blows. In order to function properly the user should always use SDS drill bits, these make the sds drills safer in regards to minimizing hammer slips.
There are certainly a great deal of advantages when it comes to using a hammer drill over a conventional one. The sds hammer drill can drill through and tackle jobs that 90% of normal drills either cannot manage or take alot more time to complete. Compared to a traditional drill, you will be able to finish well ahead when using this type of drill.
Additionally, SDS drills are manipulated through the use of different modes. If you wish to drill at normal speed without too much action, you are able to opt for a max speed of 1500RPM or slower if required. If you like you can also select a hammer only mode, sometimes known as "roto stop". When using this action, you must fit SDS chisel attachments or perhaps use micro drills such as a concrete breaker. It is best to use this mode for light drilling, the removing of tiles or bricks, or even making electrical socket cut-ins or cable runs.
Many brands that are sold are fitted with safety clutches which have the ability to shut the power off the drill if it jams in any material being drilled.
When searching for an ideal drill, look for an ideal weight, which is around the 2kg to 4kg mark. You should purchase the best sds drill that you can comfortably afford. They range in price from under a hundred pounds to well over a thousand for a very high end one.
Additional characteristics that sds drills can have include speed control and also rotation lock control which allows the user to lock the chisel in place so can't be moved.
